Tibia, A method for determining the chemical composition of a material is Rutherford backscattering (RBS), named for the scientist who first discovered that an atom contains a high-density positively charged nucleus, rather than having positive charge distributed uniformly throughout (see Chapter 39). However, the cell often needs to transport materials against their concentration gradient. This process is active because it requires the use of energy (usually in the form of ATP). In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. Why is energy important to a living organism?
